These materials are intended to provide meaningful experience in basic transducers for students of modern technology. The topics included provide exposure to: basic principles of measurement as well as pressure, temperature, level, rate, photoelectric, and sound transducers. The materials are presented in an action-oriented format combining many of the features normally found in a textbook with those usually associated with a laboratory manual.

This manual, along with the others in the Electromechanical Technology Series, is the result of six years of research and development by TERC, a national nonprofit, public service corporation with headquarters in Cambridge, Massachusetts. It has undergone a number of revisions as a direct result of experience gained with students in technical schools and community colleges throughout the country.
